Abstract (en)
[origin: EP0041405A2] A tubular polymerization reactor (4) comprises a feed opening (8) for a polymerizable material at one end portion, a withdrawal opening (6) for the resultant polymer at the other end portion, a tubular reaction space within the reactor (4) extending from said feed opening (8) to said withdrawal opening (6), and a rotary member (3) disposed within the reaction space and extending therealong with some clearance from the inner wall surface of the polymerization reactor (4); characterized in that(i) the length-to-diameter ratio (ℓ/<sup>r</sup>t) of the tubular reaction space is at least 20/1, and(ii) the rotary member (3) is coil-like. When the reactor (4) is used in a polymerization process polymerizable material is fed into feed opening (8) and polymer is withdrawn from withdrawal opening (6), the peripheral speed of a cylinder defined by the rotation of the coil-like member (3) being not less than 0.3 meters/sec.
